Valerenga won the match against Brann 2-1 two weeks and a subsequent home victory, delivered by a fully clothed Deila, has lifted the capital club five points above the top-flight drop-zone with six games remaining.

Deila has said he will not regularly appear naked as not to reduce the “surprise effect” of the motivational manoeuvrer.

That is a decision likely welcomed by his players.

“No one was really disappointed that he has not done it again since,” captain Christian Grindheim said.
